The Ollo SDK follows one simple flow:

Everything runs locally and requires no calibration.
Create a developer account: Grants access to builds for Unity, Unreal, Godot and native C++.
Download the SDK for your engine: Once you sign up, you'll get direct engine-specific download links in your dashboard. Each build includes headers, binaries and a tiny example scene.
Grab your license key: Keys are engine-agnostic and work locally, offline and per-machine.
All processing runs locally with minimal runtime overhead. Designed to fit naturally into real-time gameplay systems.
